动态方式是采用pthread_mutex_init()函数来初始化互斥锁，API定义如下： int pthread_mutex_init(pthread_mutex_t *mutex, const pthread_mutexattr_t *mutexattr) 其中mutexattr用于指定互斥锁属性（见下），如果为 NULL 则使用缺省属性。 pthread_mutex_destroy()用于注销一个互斥锁，API定义如下：
NDIS_MUTEX is a wrapper for KMUTEX. Return value. None. Remarks. NDIS network drivers should use the NDIS_INIT_MUTEX macro to initialize a mutex. The pthread_mutex_init() function creates a new mutex, with attributes specified with attr.

The method using an init function is preferable when you need special properties for your mutex, such as being recursive e.g or being shareable between processes, not only between threads. The object pointed to by mutex is set to an identifier of the newly created mutex. type must have one of the following values: mtx_plain - a simple, non-recursive mutex is created. mtx_timed - a non-recursive mutex, that supports timeout, is created. An implementation may cause pthread_mutex_destroy () to set the object referenced by mutex to an invalid value. A destroyed mutex object can be reinitialized using pthread_mutex_init (); the results of otherwise referencing the object after it has been destroyed are undefined. It shall be safe to destroy an initialized mutex that is unlocked.
Semaphores were only in older 2.6.16 kernels, now mutex replace with earlier semaphores implementation, check the below api's and linux/mutex.h header.

Semafor. Olika trådar får köra post respektive wait. En semafor kan användas till mutual Mutex. Endast tråden som kört lock får köra unlock. Semafor.
If attr is specified as NULL, all attributes are set to the default mutex attributes for the newly created mutex. The pthread_mutex_init() function initializes the specified mutex. If attr is non-NULL, the attributes specified are used to initialize the mutex. If the attribute object is modified later, the mutex's attributes are not affected. If attr is NULL, the mutex is initialized with default attributes, as specified for pthread_mutexattr_init().

An mutex_lock. This is used to lock/acquire the mutex exclusively for the current task. If the mutex is not available, the current For each read we pick a key to access, Lock() the mutex to ensure exclusive access to the state , read the value at the chosen key, Unlock() the mutex, and The same thread can consume a mutex multiple times without locking itself. Each time the owning thread acquires the mutex the lock count is incremented.
